Description

Electric vacuum cleaner

The present invention relates to a vacuum cleaner.

In a conventional cyclonic vacuum cleaner, a handle is pivotally supported on the upper part of the dust collector. A fixing claw is provided at the end of the handle. When the user attaches the dust collector to the vacuum cleaner main body, the dust collector is placed in a vertical state and attached to the vacuum cleaner main body. Thereafter, the user aligns the fixed claws of the dust collector handle with the engaging portions of the cleaner body. Then, while the user engages the fixing claw of the handle and the engaging portion of the cleaner body, the user rotates the handle from the inverted state to the stored state, and holds and fixes the dust collector to the cleaner body (for example, Patent Document 1).

However, the conventional vacuum cleaner has room for improvement from the viewpoint of improving usability. That is, in the conventional vacuum cleaner, the dust collector cannot be attached to the vacuum cleaner body with the handle turned upside down. Therefore, when the dust collector is attached to the cleaner body, the user moves the handle from the inverted state to the retracted state while aligning the positions of the fixing claws of the dust collector handle and the engaging portion of the cleaner body. It was necessary to rotate. Therefore, it takes a lot of time and effort to mount the dust collector on the vacuum cleaner body.
